'Application filed November 1, 1906. Serial No. 341,557.

To all whom it may concern:

Bc it known that I, AUGUSTUS Lnrcns'rsn Moss, a citizen of the UnitedStates, andw'a resident of Sandusky, in the county of Erie and StateofOhio, have invented a new and Improved Wrench, ofwhich the following isa full, clear, and exact description.

The object of the invention is to provide a new and improved wrench,more especially' designed for turning bolts, nuts and other articles anddevices, notably, however, such as are located in inconvenient placesnot readily accessible by an ordinary wrench.

The invention consists of novel features andparts and combinations ofthe-same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical 'embodiment of the invention is represented in theaccompanying drawings forming a part of this specification. in whichsimilar characters of reierence indicate lcorresponding parts in all theviews.

lfiglu'e l is a side elevationoi the improvement;

Fig. 2 is a sectional side elevation ofthe same; Fig. 3 is a transversesection of the same on the line 3---3 of Fig. 2; Fig. 4 is a sectionalplan view of the saine on the 'line 4--4 oi Fig. l, and Fig. 5 is aperspective view of one of the interchangeable heads.

Ihe casing A ofthe Wrench is provided with a cover A and a handle A2 onwhich is mounted to turn a. hand sleeve l secured to the shaft Cextending within the hollow handle A" andi-the casing A, and journaledin suitable bearings therein. On the inner end of the shaft (l issecured-a worin or spiralgear wheel l) in mesh with a spiral gear wheelE havingts shaft E journaled in the back and cover A of the casing A.The gear wheel ll is in mesh with a gear wheel F having its h ub]"\jourualed\'in the back and. cover A 'of the casing A, and the saidgear wheel is provided with a` polygonal opening F2 so aste forni awrench headv adapted to engage the nut, bolt or other article or deviceto be turned. 'i

New in order to use the wrench it is only necessary to engage theopening F2 with the bolt, nut or other article or device and thenturnthe hand sleeve B in the proper direction, so as to rotate the shaft Cand consequently turn the gearing, of which aA member carries a wrenchhead, so that the bolt or nut, yarticle or-other device is turned in thedesired direction with a view to screw the same up or to unscrew itaccording to the direction in which the hand` sleeve Ffis turned. Y

Now in order to permit the use of the wrench for bolts, nuts and thelike o smaller size, use is made of supplementary wrench' heads G`having openings of corresponding size and such, for instance, as shownin Figs. 4 and 5. In this case it is only necessary to insert the wrenchhead G- into the openingF the wrench head G having a. polygonalbody,`the outside of which fits the walls of the opening F2, so thattl1e fsuppl ementary wrench head turns with the gear wheel F. The wrenchhead G has a polygonal opening for engaging a bolt, nut or the' like.One end of the body-of the wrench head G is provided with a angeG andthe other end has a threaded portion -G2 on which` screws a nut G3, tosecurely hold the wrenchheadG against lat- 'eral motion, as will hereadily understood byreierence to Fig. 4. As shown in this viewtheil'ange G and the nut G2 engage the outer faces of the gearwheel F.so th at the auxiliary wrench head Grv is held. against lateral movementbut turns .with the gear wheel F when the latter is rotated by theoperator turning thehand sleeve B in either a forward or a backwarddirection.

Other suitable devices may be employed for fastening the interchangeablewrench head G to the gear wheel F, and hence I do not limit myself tothe particular construction shown and above described.

By the use of the intcrmcdiategear E a powerful rotation of the Wrenchhead can be had, so as to readily loosen tight mits, bolts and the like,and to permit of firmly screwing up bolts, nuts and the like whenever itis desired to d0 S0.

The wrench shown and described is very simple and durable inconstruction, and as no-swinging movement of the handle is required itis evidentthat the wrench can be used to great advantage for turningbolts, nuts and the like located in places not readily accessible to anordinary wrench. The wrench 1nayf, however, be used as an ordinarywrench.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: y

1. A wrench .-omprisin ,r :i casing, anu-euch hond mounted lo turn inthe said easing und adapted to engage the :n-tiele to be turned, agearing for turning 'the said head. und u hand sleeve mounted to turn onkthe casing for actuating lthe said gearing and means for-reducing. thesize of the wrench head, said means comprisingr supplementor-y wrenchheads of n diameter to enter the said wrench head. snld supplementaryheads -being provided with u ilnnge upon one end thereof undvhuvlng theother end threaded, and a lult for engaging the threaded end whereby tosecure the wrench head in place.

wrench comprising n easing having avliundle, a build sleeve mounted toturn on the outer end of the said handle, n shaft attached to the saidhund sleeve and journnled in the casing and its handle. u gearingconnected with the suid shaft. und :l wrench head on n member ot' the4said gearing und extendingr on opposite faires of the snld easing undmeans for reducing the size of the 'wrench head, snid menus comprisingsnpplementur)1 wrench heads of a diameter to enter the suld wrench head.said supplementary heads beingr provided with a flange upon une endthereof und having,F the other end threaded. und :I .nnt for engagingthe threaded 'end whereby to secure the wrom-li head in place.
